Need specific columns while fetching data from Pendo

Hi Team,

I want to pull data from Pendo and I need few column in my data. Below are the column I need.
visitorId
visitor_name
agency_name
days_active
Times_on_the_Site
accountId
date

I am using below details to fetch data
url = "https://app.pendo.io/api/v1/aggregation"
data = "{\"response\":{\"mimeType\":\"application/json\"},\"request\":{\"pipeline\":[{\"source\":{\"events\":null," \
"\"timeSeries\":{\"first\":\"now() - 30 * 1000 * 60 *60 * 24\",\"count\":-1,\"period\":\"dayRange\"}}}]}} "

But in here I am getting below columns
'accountId'
'appId'
'day'
'pageId'
'numEvents'
'numMinutes'
'remoteIp'
'server'
'userAgent'
'visitorId'
'parameters'

Is there a way to get above columns?
